MEANS FOR CRESTING AN ARROW SHAFT Filed Sept. 28, 1962 INVENTOR. JZEEV C 7?? /1/7' BY Qmzmi United States Patent Oflice Patented August 30, 1966 3,269,355 MEANS FOR CRESTING AN ARROW SHAFT Jerry C. Tarrant, Macomb County, Mich. (5334 Casmere, Warren, Mich.) Filed Sept. 28, 1962, Ser. No. 227,009 3 Claims. (Cl. 118-219) This invention relates to the art of cresting arrows.

Heretofore in this art, it has been necessary to manually apply an artists brush to a rapidly rotating arrow shaft in order to apply a crest thereon and a good deal of skill is required in spite of the steady rests that are supplied with the better arrow cresting devices. In these prior art devices the speed of the rotating shaft is of the order of several hundred revolutions per minute and it doesnt require much of a slip to spoil an otherwise acceptable cresting job. Moreover, even without a slip spoilage can result from the shaft being out of true. Spoilage is extremely annoying if it occurs on the last of several crests .as in the use of such devices only one crest can be applied at a time. Unfortunately the most difficult task must be done last which is that of pin striping, i.e. applying hairline border stripes at both ends of each of the previously applied crests that have been allowed to dry.

Accordingly, the principal object of the present invention is the provision of method and means for simultaneously applying a plurality of crests to a rotating arrow shaft so as to invariably produce substantially perfect crests with relative ease and without requiring developed skill.

The foregoing and other objects of the invention will appear during the course of the following description taken in conjunction with the accompanying drawings in which:

FIG. 1 is a longitudinal sectional view with parts in elevation of an arrow cresting device embodying the present invention;

FIG. 2 is a fragmentary plan view of the device of FIG. 1; and

FIGS. 3 and 4 are fragmentary sectional views of the device of FIG. 2 taken, respectively, along the lines 33 and 4-4 thereof.

Referring to the drawings in greater detail, 10, indicates several knurled paint wheels of selected widths and uniform diameter which are supported for rotation in common about a shaft 13 on which the wheels are fast, in the instance. The shaft 13 is rotatably supported at its opposite ends in a paint tank 14 so that the wheels dip into lacquer when the tank is sufficiently filled as shown and apply the same during the cresting operation in respective bands or crests 15 on an arrow shaft 16 which is supported for rotation about its own axis. The portion of the arrow shaft that extends over the cresting area which includes the wheels 10 is supported on bearings that span said area and a force is applied to the shaft to urge it against such bearings. Each such hearing as it supports the shaft captures it by the rollers 24 and 25 which bear against opposite sides of the rotating shaft as shown in FIG. 3. The rollers 24 and 25 are carried on supports which in turn are mounted on a side wall 21 of an assembly 22. The support 23 for the roller 24 is pivotally mounted on such wall 21 and is yieldably urged by a tension spring to rotate so that the roller 24 bears against the roller 25 when the device is not in use. When an arrow shaft is interposed between the rollers 24 and 25 as shown for supporting it for rotation the distance over which it is true is extended from its chucked end to include said cresting area. It has been found to be the co-action between the two bearings shown and the chuck which is responsible for keeping the shaft true from its chucked end to the bearing furthest from said chuck as the shaft rotates on its axis. The tail end of the arrow is gripped in a chuck 27 which is rotatably driven at a speed of the order of 18 rpm. by a motoir 28 through a gear reducer 29 which serves as a mount for the motor and itself is mounted on an upright 30 at one end of the device. The upright 30 extends between tubular members 31 forming a part of the base of the device which are supported on legs as shown to raise them sufficiently so that the assembly 22 can slidably reciprocate on them. The walls 21 each support a pair of rollers 32 that are spaced from each other and so located on the inside of the wall to ride in a track 33 formed on a side of a carrier 35. There are two such tracks as shown by which the carrier is rollably supported on the assembly for reciprocation transversely of the base. The carrier 35 removably holds the paint tank and by its combined movement the wheels 10 can reach substantially any location on the arrow shaft.

In operation of the device the arrow shaft is gripped in the chuck 27 and the assembly 22 is moved longitudinally of the base until the rollers are brought lengthwise of the arrow shaft to where the crests are desired and the assembly made fast against the members 31 by a lock screw 36. The carrier 35 is then unlatched from its stored position at the front of the assembly where it is secured by the latch 37 when not in use and held against the pulling by the tension springs 38 which connect the carrier to the rear of the assembly as shown. The motor 28 is then energized to rotate the arrow shaft and the wheels 10 are eased against the shaft until they rotate and produce the crests 15. The carrier is then returned to its stored position and the crested arrow removed from the device. Pinstripe crests on previously applied and dried crests are easily applied in the same manner with a very thin wheel brought into engagement with the arrow on a side of each of the crests successively until all have been crested with pinstripes.

The wheels 10 can move in one plane only which, in the instance, is the horizontal plane and are fixed against movement in either of the opposite perpendicular directions while the arrow shaft except for axial rotation is substantially immobile during movement of the wheels 10 into frictional engagement therewith.

It will thus be seen that there has been provided by the present invention a method and means of simultaneously applying a plurality of crests to an arrow shaft in 'which the foregoing object and advantages have been successfully accomplished. It should be understood that modifications, variations and changes may be'resorted to without departing from the spirit of the invention as set forth in the appended claims.

What is claimed is:

1. In an arrow cresting device in which an arrow shaft is rotatably driven at one of its ends about its own axis, wheel means to apply paint in crests to the rotating shaft, said wheel means comprising a plurality of spaced wheels fast on a common shaft, a paint tank supporting the common shaft for rotation about its own axis so that said wheels can rotate in a supply of paint carried in the tank, and means to move the tank so that it is reciprocable axially and perpendicularly of the arrow shaft.

2. Apparatus as claimed in claim 1 including means to secure the tank fast axially of the arrow shaft while providing for its reciprocable movement perpendicularly thereof.

3. Apparatus as claimed in claim 2 including means to yieldably urge the tank perpendicularly of the arrow shaft so that said Wheels are brought into rotating engagement with the rotating arrow shaft by decreasing resistance to said yielda'ble means.
